sorry bro
have you told anyone in your life about this problem who can hold you accountable? perhaps your family or your pastor?
If you haven't already you need to go and throw away, pour out all your alcohol in the house so you don't have it readily available to you when you feel the urge to drink. Also handing someone your wallet to look after for awhile so you'll be unable to go out and buy it may be another necessary step you need to take. If you have any buddies that you like to go out drinking with tell them in no uncertain terms you're trying to quit drinking and cannot go drinking with them. Hopefully if they're true friends they will help hold you accountable to that and if not then those may be friends you'd be better off without at least until you're able to get control back over that area of your life.
Also remember to take this to the Lord in prayer. I'm sure you're already doing that but remember to leave this at the cross rather than holding it as a burden and something to make you hate yourself for. God doesn't hate you and He's always there with open arms to forgive you. Yes drunkenness is a sin that you need to repent of if you haven't already but it is no worse than any other sin and it isn't unforgiveable. Christ's blood covers that too and Like John says when you confess that sin to Him you are cleansed of all unrighteousness. God doesn't see that sin anymore because when He looks at you He sees the righteousness of Christ.
If we confess our sins, He is faithful and just to forgive us
our sins and to cleanse us from all unrighteousness. - 1 John 1:9
Remember to go to Him in times of temptation as well. I know it seems like the obvious choice but the Bible tells us that Christ is a sympathetic mediator who has been tempted on all points as we were, He knows what you're going through ans He's there to be your strength when you're weak. Thats one of the great things about being a Christian is we don't have to rely on our own strength to over come our temptations or weaknesses.
No temptation has overtaken you except such as is common to man; but God
is faithful, who will not allow you to be tempted beyond what you are able, but with the temptation will also make the way of escape, that you may be able to bear
it. - 1 Cor 10:13
14 Seeing then that we have a great High Priest who has passed through the heavens, Jesus the Son of God, let us hold fast
our confession. 15 For we do not have a High Priest who cannot sympathize with our weaknesses, but was in all
points tempted as
we are, yet without sin. 16 Let us therefore come boldly to the throne of grace, that we may obtain mercy and find grace to help in time of need. - Hebrews 4
praying for you bro
